Abstract
L'invention se rapporte à un procédé de modification d’un flux vidéo, caractérisé en ce qu’il comprend les étapes suivantes :- recevoir un premier flux vidéo comportant des successions d’images à diffuser prises par au moins un appareil de prise de vue ainsi que des données associées de position de prise de vue (301),- déterminer pour la succession des images à diffuser un flux de découpe (303), le flux de découpe indiquant pour chaque image à diffuser des niveaux de transparence en vue d’une opération de combinaison du premier flux vidéo avec un deuxième flux vidéo sous forme d’une ou de plusieurs images,- recevoir du deuxième flux vidéo (307), - combinaison (309) du premier flux vidéo avec le deuxième flux vidéo en tenant compte des données associées de position de prise de vue ainsi que du flux de découpe, lors de l’opération de combinaison le premier flux vidéo étant traité comme fond tandis que le deuxième flux vidéo est traité comme contenu de remplissage.Figure pour l’abrégé : Fig. 11The invention relates to a method for modifying a video stream, characterized in that it comprises the following steps:- receiving a first video stream comprising successions of images to be broadcast taken by at least one camera view as well as associated shooting position data (301),- determining for the succession of images to be broadcast a cutting stream (303), the cutting stream indicating for each image to be broadcast levels of transparency with a view to an operation of combining the first video stream with a second video stream in the form of one or more images, - receiving from the second video stream (307), - combining (309) the first video stream with the second video stream, taking account of the associated shooting position data as well as the cutting stream, in the combining operation the first video stream being treated as the background while the second video stream is treated as the filler content.
